Using Spacecraft Signals to Measure Sulfur Species on Venus
Upcoming missions to Venus will seek trace amounts of sulfur-containing molecules that can help us study the planet’s sulfuric acid clouds and search for active volcanoes.

Giving Stars a Brake
Astrobites reports on how stellar rotation is slowed by stellar winds via magnetic braking, with a special focus on stars cooler than the Sun.
Investigating a Bright Flare in a Nearby Galaxy
Astronomers have seen an extraordinarily bright, long-lasting radio flare in the center of a nearby galaxy. Could this be evidence of a star being shredded by a supermassive black hole?
Searching for a Star That Survived a Supernova
Researchers have discovered a potential companion to a star that exploded 8,000 years ago. Its characteristics raise interesting questions about which stars are able to donate enough material to trigger a supernova.
A New Look at Gamma Rays from Our Galaxy’s Next-Door Neighbour
Astrobites reports on a new investigation of the Andromeda Galaxy’s gamma-ray emission that reveals it to be far different from originally thought.
The First Y+Y Binary: Cool Brown Dwarfs Come in Pairs
All scientists love to label and classify the natural world, but brown dwarfs resist such artificial labels and can’t be cleanly categorized as either a star or as a planet. Now with JWST though, astronomers are getting their best look yet at these enigmatic worlds.
TESS Detects Pulsating Stars in the Pleiades Cluster
Astronomers pair data from a planet-hunting spacecraft and a stellar-position plotter to track down pulsations in a nearby star cluster.
Biases from Bulging Planets
Astrobites reports on what we might be getting wrong by assuming that slightly squished planets are instead perfectly round.
More Supernova Detections May Be on the Horizon with High-Energy Neutrinos
In rare cases, certain supernovae might produce high-energy neutrinos, allowing our neutrino detectors to track down exploding stars out to greater distances.
Could Some High-Redshift Galaxy Candidates Actually Be Supernovae?
Some high-redshift galaxy candidates in JWST images are curiously point-like. New research investigates whether these sources might be supernovae instead.
Featured Image: How Do Supermassive Black Holes Eat?
New high-resolution three-dimensional simulations explore the nature of accretion onto supermassive black holes in elliptical galaxies.
Planning for Touchdown: New Maps of the Moon’s South Pole
When the next moonwalkers land near the lunar south pole, they’re going to need a map. With a possible Artemis III landing just a few years away, planetary scientists are hard at work trying to make one fit for spacesuit-clad geologists.
